SO YA WANNA BUILD A GLASS BOW ?

[Roy from Pa]

191 is purty quik ole boy.
Good job.

[Buemaker]

Smokin allright.  

[Al Dean]

How loud at 191?

[stickmonkey]

Its looking good Kenny and I like the drawn profile for sure. Do you happen to know the total thickness of the tips at the string grooves minus the overlays?

[kennym]

Thank you guys, I'm fairly happy with this one(except no clear glass) LOL

I just shot it in the shop again(raining), it seems as quiet as any, but they always seem louder outside to me, I will give a full report when I'm all done and have a finish and rest on it.

To get the 9gpp I was shooting an old carbon express 45/60  with 175 up front. Not sure what I'll end up with for it.(EDIT, that arrow was for the 30" test)

The arrow for the 28" test was a cx heritage  150 with 115 up front.

Shane, if you deduct the tip wedge part of the superlam and do a bunch of figuring I came up with .265 at nock by actual measure and a bunch of math.

Then I did it the easy way and took .003 per inch for 32" for limb length off the butt stack of .355"and got .259 so in that area....

[kennym]

Oh, also checked at 30" draw with 9 gpp, it shot 201 fps there, so you longarmed guys have a big advantage on us others...

It gained 5.5# in the 2" from 28 to 30 so that works too. From 52.72# to 58.22 #

[Roy from Pa]

How's this ole boy?  
 

[stickmonkey]

Thanks kenny so with the tip wedge in somewhere around .300- 315. the reason I asked was I am doing some comparisons with tip thickness and stiffness to help dial in this 56". You are right in line where I am with most of my tip thickness so I am going to go a little less and see if its still as stiff as I want it.

[kennym]

Go for it Roy!! LOL

Shane, I checked it and with wedge was .320

[stickmonkey]

Yes spot on to what I have on the 56". Thank you Kenny

[kennym]

OK, the bow is done but I'll catch up on some more details...

Here I'm going to radius the corner from shelf to side plate, same file I use on nocks...

 

You can see where I cut a radius in the corner, then you remove material from side plate and shelf to leave a nice radius corner. I know some guys have power tools to do this, and if I built a lot of bows I would too.It takes a bit of time...

 

Easier to work on if you can hold it still, here I have cleaned up the radius, shelf, and side plate area...

 

Now the test....

Cranking the shop built hooter shooter back,, measuring the draw length,, and shooting thru the chrono.......

 

 

 

Results, the boat winch on the shooter came up a fuzz short of 28" on this shot and about the same long on next which read 192 so I'm calling it 191 fps with a 9 gpp arrow at 28" draw length...

 

[Mad Max]

Nice

Roy are you going to make a Take Down wood tri-lam or Glass?

[Crittergetter]

Dang it, now I'm gonna have to make me one of those shooters!  Lol
Good numbers Kenny!!!

[Bvas]

Slounds like ya got yourself a shooter!!
Nicely done.

[Carpdaddy]

Very nice, that's a shooter for sure.

[kennym]

Thanks guys, I will re test when I get some arrows tuned to  it.

Sprayed it with the Duplicolor matte wheel finish I had on hand, looks real good but didn't get any pics before dark...

[kennym]

And for the record, I discovered a limb wasn't tracking to suit me, so worked on it a bit and lost another lb or so. Then sanded good , so I expect it to be around 50#

[Roy from Pa]

Nice bud..

Not telling ya maxi boy..  

[choochoou]

I'm sure you may have covered this already but I'm wondering please this design faster smoother then the previous 62 to 64
